Weather in May
Temperature
May, known for its average high temperature of 32.6°C (90.7°F) and an average low temperature of 25.9°C (78.6°F), is the warmest month.Heat index
May's heat index is computed to be a blisteringly hot 41°C (105.8°F). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Heat index determinations are made taking into account the shade and light air movements. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
